Error on generating GUID, portion of code from repository to set Id
Class EfCoreRepository
`protected virtual void CheckAndSetId(TEntity entity) { if (entity is IEntity
protected virtual void TrySetGuidId(IEntity<Guid> entity)
{
if (entity.Id != default)
{
return;
}
EntityHelper.TrySetId(
entity,
() => GuidGenerator.Create(),
true
);
}`
the guid generated does not match the pattern for GUIDs [a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[1-5][a-fA-F0-9]{3}-[89abAB][a-fA-F0-9]{3}-[a-fA-F0-9]{12} based on https://datatracker.ietf.org/doc/html/rfc4122
Partial solution
public class GuidValueGenerator : ValueGenerator<Guid> { private readonly IGuidGenerator _guidGenerator; private readonly string pattern = @"^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[1-5][a-fA-F0-9]{3}-[89abAB][a-fA-F0-9]{3}-[a-fA-F0-9]{12}$";
public override bool GeneratesTemporaryValues => false;
public GuidValueGenerator()
{
var options = Options.Create(new AbpSequentialGuidGeneratorOptions());
options.Value.DefaultSequentialGuidType = SequentialGuidType.SequentialAtEnd;
_guidGenerator = new SequentialGuidGenerator(options);
}
public override Guid Next(EntityEntry entry)
{
var result = GenerateNextValue();
string json = JsonConvert.SerializeObject(entry.Entity);
WriteOnText(result.ToString());
WriteOnText(json);
return result;
}
public Guid GenerateNextValue()
{
var result = _guidGenerator.Create();
if (!Regex.IsMatch(result.ToString(), pattern))
{
return GenerateNextValue();
}
return result;
}
public void WriteOnText(string newGuid)
{
string filePath = @"D:\guid-lines.txt"; // Replace with your file path
// Open the file for writing
using (StreamWriter writer = new StreamWriter(filePath, true))
{
writer.WriteLine(newGuid);
}
}
}

hi
the guid generated does not match the pattern for GUIDs
This is abp implement.
https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.Guids/Volo/Abp/Guids/SequentialGuidGenerator.cs#L14
If you think there is an error you can replace it with your own. : )
